So, you picked up Gitar Hero World Tour, and had your buddies over for some co-op head banging action. Imagine your disappointment when a mere trifle of the game's 84 tracks are available from the get go. Worry no longer, folks, there's hope yet. A cheat code is available that allows all the songs to be selected. This code must be entered from the Options > Cheats > Enter Cheat menu:
Blue - Blue - Red - Green - Green - Blue - Blue - Yellow
I normally don't condone cheats, but I'd pretty much take any steps necessary to not have to play "On the Road Again" by Willie Nelson on drums again. "Guitar Hero", my big toe!
In other news, the launch trailer for the game is up, and we have it embedded for you at your convenience after the break.
